As has been made pretty clear by this point, I don't really follow football. Or play a lot of it. Last time I think I threw a football was at some point in high school; I'm sure it didn't go very far. So a $20
Virtual Distance Football
would probably just be a reminder of my terrible lack of quarterbacking skills.

You see, it's a pretty standard foam football but with a distance sensor embedded in it. Fire off your best hail mary pass and the LCD will tell you how much yardage you just threw for. I'd probably advise against using it in an actual game, as stopping to marvel at your
cannon-like
arm is the kind of thing that's likely to get you sacked.
